Stack Visualizer – Expression Converter & Evaluator

📌 Overview

Stack Visualizer is a web-based educational tool designed to help users understand stack-based expression conversion and evaluation. The application visually demonstrates how stacks operate during infix, prefix, and postfix conversions and evaluations, step by step. It is especially useful for students learning Data Structures, as it bridges theory with interactive visualization.

✨ Features

  • Infix ↔ Postfix ↔ Prefix conversion
  • Infix, Prefix, and Postfix evaluation
  • Step-by-step stack visualization
  • Controls for Prepare, Play, Pause, Next, Previous, and Reset
  • Clear display of stack state, TOP pointer, and output
  • Supports operands as letters (conversion) and numbers (evaluation)

🧩 System Architecture

  • Frontend: HTML, CSS, JavaScript

    • User input interface
    • Stack and output visualization

  • Backend: C-based stack processing logic

    • Expression conversion algorithms
    • Expression evaluation using LIFO stack principle

Frontend and backend communicate through structured requests and responses to generate step-wise execution data.

⚙️ Technologies Used

  • HTML
  • CSS
  • JavaScript
  • C (Stack-based algorithms)

🚀 How It Works

  1. User enters an expression and selects an operation
  2. The frontend sends the request to the backend
  3. Stack-based algorithms perform conversion or evaluation
  4. Each push/pop operation is recorded as a step
  5. The frontend visualizes these steps dynamically
  6. Final converted expression or evaluated result is displayed

🎯 Use Case

  • Learning stack operations
  • Understanding expression parsing
  • Visualizing algorithm execution
  • Academic mini-projects and lab demonstrations
